That may sound cool until you go through a door accidentally, or you make a door in a wall that some part of your psychology still needed to believe was solid.
Please choose responsibly to read this website. Every space is connected to every other space, which means that you can get to anywhere from here... if you know about doorways.
The thing with doors is that if you make or find a doorway and do not go through the doorway, the doorway may close in front of you and you may never be able to make or find that doorway again.
On the other hand, if you make or find a doorway and you are close enough to the doorway to go through the doorway... and you decide to go through... and you actually do go through, the doorway may close behind you and you may never be able to find your way back to the way you were before.
This is the game of doorways. You have been warned.
